Re: [help-gengetopt] feature request: add new --show-help and --show-version options

[Lorenzo Bettini]

Hi

a tentative version implementing --show-help and --show-version can be 
found temporarily here:

http://rap.dsi.unifi.it/~bettini/gengetopt-2.13rc1.tar.gz

notice that, if package and version are not specified in the .ggo file, 
you have to pass them explicitly to gengetopt with options --set-package 
and --set-version.

this 2.13.rc1 also contains the implementation of enumerated options 
(where you specify the possible strings that can be passed to an option).

I look forward to receiving feedback :-)

cheers
        Lorenzo
